Start codon targeted (SCoT) polymorphism reveals genetic diversity in wild and domesticated populations of ramie (Boehmeria nivea L. Gaudich.), a premium textile fiber producing species

Twenty-four start codon targeted (SCoT) markers were used to assess genetic diversity and population structure of indigenous, introduced and domesticated ramie (Boehmeria nivea L. Gaudich.). A total of 155 genotypes from five populations were investigated for SCoT polymorphism, which produced 136 amplicons with 87.5% polymorphism. Polymorphism information content and resolving power of the SCoT markers were 0.69 and 3.22, respectively. The Indian ramie populations exhibited high SCoT polymorphism (> 50%), high genetic differentiation (GST = 0.27) and moderate gene flow (Nm = 1.34). Analysis of molecular variance identified significant differences for genetic polymorphism among the populations explaining 13.1% of the total variation. The domesticated population exhibited higher genetic polymorphism and heterozygosity compared to natural populations. Cluster analysis supported population genetic analysis and suggested close association between introduced and domesticated genotypes. The present study shows effectiveness of employing SCoT markers in a cross pollinated heterozygous species like Boehmeria, and would be useful for further studies in population genetics, conservation genetics and cultivar improvement.

Antifungal efficacy of plant essential oils against stored grain fungi of Fusarium spp.

The control potential of seven plant essential oils was evaluated against Fusarium proliferatum (Matsushima) Nirenberg and Fusarium verticillioides Sheldon. The fungicidal activity was assessed through microtiter plate assay to determine the minimum inhibitory and fungicidal concentration of essential oils. The essential oil of Mentha arvensis was adjudged as best for inhibiting the fungal growth, while oil of Thymus vulgaris and Anethum graveolens showed high efficacy in terms of fungicidal activity. The oil of M. arvensis and T. vulgaris also showed good inhibition activity in agar disc diffusion assay. M. arvensis essential oil was analysed for its composition using gas chromatography/mass spectrometry revealing menthol (63.18xa0%), menthone (15.08xa0%), isomenthyl acetate (5.50xa0%) and limonene (4.31xa0%) as major components. Significant activity of M. arvensis essential oil against F. proliferatum and F. verticillioides isolates obtained, pave the way for its use as antifungal control agents.

A triad of developmental anomalies-an unusual case.

A fissured tongue and ankyloglossia or tongue-tie is a congenital anomaly of the tongue. Mandibular tori is a proliferation of the peripheral bone that results from a localized, excessive growth of ossein [1, 2]. n nA 27 years old male patient reported to the Department of Oral Medicine and Radiology, NIMS Dental College, Jaipur, with the complaints of a difficulty in swallowing food and difficulty in speaking, which were there since childhood. On intra-oral examination, a high and thick lingual frenum was observed, which restricted the tongue movements and caused a inability in protruding and touching the palate [Table/Fig-1]. The dorsum of the tongue presented with a deep vertical fissure which extended till the tip and multiple connecting grooves in the transverse direction [Table/Fig-2]. n n n n[Table/Fig-1]: n nShows Ankyloglossia n n n n n n[Table/Fig-2]: n nShows Vertical fissure on tongue till the tip and horizontal groves n n n nOn examining the floor of the mouth, an oval swelling was found to be present on the right and left sides below the alveolar crest, which extended from the canine and the premolar regions, with the overlying mucosa being pale as compared to the surrounding mucosa. On palpation, the swelling was found to be hard in consistency, with the overlying mucosa being firm, non-tender and fixed [Table/Fig-3]. A mandibular occlusal radiograph was taken for the swellings and it revealed bulging of the bone with a normal radiographic bone pattern [Table/Fig-4]. A clinical examination revealed the reason for the difficulty in speech as ankyloglossia. Other additional findings were the presence of a fissured tongue and lingual swellings as Mandibular tori. n n n n[Table/Fig-3]: n nShows bilateral Mandibular Tori n n n n n n[Table/Fig-4]: n nShow bilateral opaque bulge of bone with normal bone pattern n n n nAnkyloglossia or tongue-tie is a congenital anomaly in which a short, lingual frenum or a highly attached genioglossus muscle restricts the tongue movements, which has an incidence rate of 5% in the normal population. Ankyloglossia is associated with other syndromes, namely, the Pierre Robin Syndrome, the Oral-Facial-Digital Syndrome, Meckel’s syndrome, the trisomy 13 syndrome, the Robinow Syndrome, the short rib syndrome, the ATR-X Syndrome, Fraser’s Syndrome, the Wiedemann-Beckwith syndrome, van der Woude’s syndrome, and the glossopalatine ankylosis sundrome [1, 2, 3]. n nFissured tongues occur in less than 10% of the normal population and they are characterized by grooves on the dorsal and lateral aspects of the tongues, that vary in depth. Fissured tongues are seen in some syndromes, namely, the Melkersson-Rosenthal syndrome, the Coffin-Lowry syndrome, Fraser’s Syndrome, Down’s syndrome, the Oral-Facial-Digital (OFD) Syndrome Type I, the Mohr Syndrome (the OFD syndrome, type II), the Pierre Robin Syndrome, the Maroteaux Lamy Syndrome, the ECC syndrome, etc. [1, 3, 4]. Mandibular tori is a proliferation of the peripheral bone, that results from a localized, excessive growth of the bone, whose incidence rate is 8% in the normal population and which is only seen in Gardner’s syndrome [1, 2]. n nTo conclude, an unusual case of a triad of dental anomalies with ankyloglossia, fissured tongue and mandibular tori, has been presented. Although many syndromes are associated with the above mentioned findings individually, it remains unclear whether such a combination occurs by chance or whether it is a true syndrome.

Banded versus Single-sided bonded space maintainers: A Comparative Study

Background: The present study is conducted to evaluate and compare the clinical performance of conventional band and loop space maintainer and fiber reinforced composite resin (FRCR) space maintainers. Materials and Methods: A total of 45 extraction sites in the age group of 6–9 years having premature loss of primary molars or indicated for extraction were selected for the study. The patients were randomly divided into three groups as Group I, in which conventional band and loop space maintainer was given, Group II and Group III (FRCR), in which FRCR (everStick CandB) and impregnated glass fibers (Interlig) space maintainers were given, respectively. Patients were recalled at 3, 6, and 12-month interval for evaluation of all the three types of space maintainer. Results: Overall success rate of Group I was 86.7%, for Group II was 80%, and for Group III was 73.3% at the end of the study. Patient acceptability was significantly higher in Group II and Group III (FRCR) as compared to Group I (Conventional band and loop). In Group I, cement loss and fracture of loop, whereas in Group II and Group III, debonding at enamel composite was the most common failure followed by debonding at fiber composite and fiber fracture. FRCR space maintainers were found to be cost-effective as compared to Group I. More linear changes and angular changes were recorded in Group I as compared to Group II and Group III but difference was not significant (P > 0.05). Conclusion: Only single (buccal) surface application of FRCR space maintainers showed almost equal clinical efficacy compared to conventional band and loop space maintainer with significantly better patient acceptability, less cost, and time taken.

Intravesical Migration of an Intrauterine Contraceptive Device with Secondary Calculus Formation

Intrauterine contraceptive devices (IUCDs) are a common form of reversible contraception owing to fewer systemic side effects and low cost, especially in a developing country like India. However, IUCDs are not without complications. Migration of a device into adjacent organs is the most morbid of all the documented complications. A patient who presents with a history that suggests loss or disappearance of an IUCD thread associated with urinary symptoms should raise suspicions that a device may have migrated into the bladder. Physicians should also be aware of possible secondary vesical calculus formation. Further radiological investigations and appropriate management are warranted. We present a case report describing the migration of an IUCD into the bladder with secondary calculus formation.

Comparison of contrast-enhanced voiding urosonography with voiding cystourethrography in pediatric vesicoureteral reflux

OBJECTIVEnVoiding cystourethrography (VCUG) has been considered as the gold standard technique for the diagnosis of vesicoureteral reflux (VUR). But, it requires fluoroscopic guidance which expose children to radiation. Voiding urosonography (VUS) is technically analogous to VCUG and has the major advantage of zero radiation exposure. This study aims to determine the efficacy of contrast enhanced-VUS (ce-VUS) with respect to VCUG in diagnosing VUR.nnnMATERIAL AND METHODSnThis study involves 30 children over a period of 3 years. All patients underwent a VCUG followed by the ce-VUS on the same day. All VUS studies were done by the same sonologist in the sonography department. The images were recorded and reviewed by the same sonologist before reporting.nnnRESULTSnThe median age of the patients was 51.53 months. There were 21 males and 9 females. On VCUG, 16 patients had no reflux, and 14 patients had reflux. On ce-VUS, 14 patients had no VUR, and 16 patients had VUR. Of the total 58 kidney-ureter units (KUUs), VUR was detected in 17 KUUs on VCUG and in 21 KUUs on ce-VUS. Thus, ce-VUS detected 4 refluxing units that were not seen on VCUG. In right KUUs, ce-VUS detected VUR in 3 units where no reflux was found in VCUG. In the 28 left KUUs, 25 units on ce-VUS showed concordance with the grade of VUR as detected by VCUG; 3 were discordant. Two units on ce-VUS showed a VUR one grade higher than the corresponding grade on VCUG and in one unit it was one grade lower. Thus, in total, ce-VUS picked up 4 cases which were missed by VCUG.nnnCONCLUSIONnce-VUS is a good imaging modality when compared to voiding cystourethrography to assess pediatric vesicoureteral reflux, in view of its superior diagnostic performance, feasibility and radiation safety for children.

Metabolic Evaluation in Pediatric Urolithiasis: Our Experience

Introduction: To determine whether the timing of voiding cystoureterogram (VCUG) in the first or the third week after a diagnosis of urinary tract infection (UTI) is important in the diagnosis and severity of VUR. Materials and Methods : In this case-control study, 72 children between 1 month and 15 years old diagnosed with their first episode of UTI were investigated over one year. The study population was divided into 2 groups of 36, early (VCUG in the first week after UTI) and late (VCUG 3 weeks after UTI), and compared the severity and incidence of reflux in both groups. Results: The prevalence of VUR was 66.6%. Twenty-two cases in the first group (61%) and 26 cases in the second group (72.2%) presented with VUR. The peak age of the disease in both groups was 1-3 years with a female predominance. The most common germ detected was E-Coli and the most common presentations were fever (87.5%) and dysuria (26.3%). Conclusions: As VUR following UTI is very common in children and is one of the most important risk factors of early hypertension and chronic renal failure, early diagnosis by VCUG seems to be useful in all UTI patients before discharge. Keywords: Urinary Tract Infection; Vesico-Ureteral Reflux; VCUG; Child.Introduction: Urinary tract infection is one of the common bacterial infections seen in infants and children. As children present with non-specific symptoms, a diagnosis of UTI is often missed or it is diagnosed very late. A wide range of organisms with varying antibiotic sensitivity patterns have been known to cause UTI. The objectives of the study were: To study the clinical profile of children with UTI To study the microbiological profile of children with UTI To study the antibiotic resistance profile of various organisms causing urinary tract infection in children. Materials and Methods : A retrospective Study was conducted in the Department of Pediatrics, CHRI, for 2 years from Jan 2014 to December 2016. The data of the children who met the inclusion criteria were collected from the case records. The collected data was tabulated and analyzed using IBM SPSS version 21. Results: Males comprised a higher proportion of subjects in <1 year and 1-5 years when compared to females. Fever was the most common presenting symptom in the study population, which was seen in 220 (80.8%) children. The number of children with a positive culture for E.coli was 154 (56.0%) and Klebsiella was isolated in 37 (13.45%) children. A high proportion of E coli and Klebsiella species showed resistance to beta lactams and fluoroquinolones. E.coli was the most common organism in all age groups. The proportion of females was higher in the E. coli group (58.9%). Klebsiella had the highest proportion of resistance to more than 2 drugs (82.4%). Conclusions: The most common age group affected by urinary tract infection is below 1 year with a male preponderance followed by above 5 years with a female preponderance. The most common isolated organism in all age groups was E. coli, which was found to be resistant to beta lactams and fluoroquinolones. Therefore, in any child with suspected, it is advised to start empirical therapy with an antibiotic, like amikacin and nitrofurantoin, and wait for the results of urine culture and sensitivity testing. Keywords : Urinary Tract Infections; Child; Clinical; Microbiological.Introduction: Urinary tract infection is a common health problem in children . Gram negative entericbacteria, mainly E –coli, are responsible uropathogens. We aimed to define the main etiologies of urinary tract infection in children considering gender and type of infection (febrile versus afebrile). Materials and Methods : We assessed the infections etiology of 648 episodes. Type of infection and etiology were compared between genders. Also, for every uropathogen, a comparison was done between febrile and afebrile infections. Chi square was used for data analysis and P values ≤0.05 were considered as a significant difference. Results: The majority of the infections by Proteus and Enterococcus species were febrile, in contrast to Citrobacter infections which were mostly afebrile. E-coli infections were significantly more prevalent in girls (P=0.0001 ) . Proteus and Kelebsiella infections were more common in boys (P=0.115 and 0.154 respectively), whereas all Enterobacter infections were seen in girls (P=0.129). A comparison was done between females and males based on the type of infection. Although febrile infections were more frequent in boys, the difference was not statistically significant (P=0.059). Conclusions: E-coli, Kelebsiella, Enterobacter and Citrobacter species (90.5%) were the main uropathogens. Infections caused by E-coli were significantly more prevalent in girls. Proteus and Kelebsiella infections were more common in boys, whereas Enterobacter species were more prevalent in girls. The majority of Proteus and Enterococcus infections (>2/3) presented as pyelonephritis, while the frequency of febrile and afebrile infections was similar for E-coli, Kelebsiella, Enterobacter and Staphylococcus species.

Materials and Methods : Between 2011 and 2012, 100xa0childrenxa0(53 boys and 47 girls) were treated forxa0urolithiasis. Clinical presentation, calculus localisation, urinary tract infection status, presence of anatomic abnormalities and urinary metabolic risk factors were retrospectively evaluated. Results: The most common clinical features on admission were restlessness/irritability (62%), flank pain (33%) and gross hematuria (4%). Twenty-one percent of patients were detected incidentally during evaluation for other conditions. Urine random tests revealed metabolic abnormalities, including hypercalciuria (56%) and hypocitraturia (64%) in most cases. Anatomic malformation (32%) and urinary tract infections (UTI)(9%) were other presentations. Conclusions: We concluded that most patients were symptomatic and hypocitraturia was the most common risk factor.

We reported a boy with Williams-Beuren syndrome and highlighted the clinical characteristics and response to treatment with Ritaline of such an individual with ADHD and voiding dysfunction. The patient was a six year-old boy with typical presentation of WBS and some psychiatric problems referred because of hyperactivity symptom and attention deficit. Children with mental retardation and WBS have a comorbidity of psychiatric disorders and kidney anomalies. Williams-Beuren syndrome can present with hyperactivity and Ritalin can improve some symptoms and voiding dysfunction. Keywords: Williams-Beuren Syndrome; Attention Deficit Disorder with Hyperactivity; Ritalin ; Methylphenidate.Many clinical studies have confirmed Procalcitonin (PCT) as a specific inflammatory marker in sepsis and bacterial infections. It is believed that PCT level is increased in various noninfectious conditions such as acute pancreatitis, major surgery, trauma and active autoimmune disease.xa0 In recent studies increased levels of serum PCT was distinguished in several kidney diseases like pyelonephritis, vesicoureteral reflux, kidney transplantation and hemodialysis. The aim of this review is to describe usefulness of PCT and practical aspect of this biomarker in nephrology field.

We describe our experience with this procedure in 30 patients managed with this procedure highlighting the factors affecting outcome in this repair. Materials and Methods: Data of 30 patients (age range 2.5-15 years) who underwent hypospadias repair in a tertiary care teaching institution from 2012 to 2015 with modified Asopa procedure (Hodgson XX technique) utilizing Transverse Preputial Island Flap by a single surgeon were reviewed and retrospectively analyzed according to age of patients, site of meatus, presence or absence or chordee, glans configuration and complications - fistula, glans dehiscence, meatal stenosis. These complications were further analyzed with respect to the various patient characteristics and GMS (Glans, Meatus and Shaft) score. Results: The mean age of presentation was 5.5 years and mean follow-up period was 22 months. The mean total GMS score was 8.5; range being 11 to 5. In total, only six patients had complications (20%). The patients with low GMS score (7 or less) had no complications. The complication rate was more in proximal hypospadias repair (n= 5/24) when compared with distal hypospadias (n=1/6). There were more complications in patients with chordee (n=4/6) and those with conical glans (n=4/6). Conclusion: Location of the meatus, presence/absence of chordee and glans configuration affect outcome in patients undergoing modified Asopas procedure for hypospadias repair. Keywords: hypospadias; Asopas procedure; Child; Complications; Outcome .A 13-year-old boy was admitted in emergency room with sever generalized edema, hypertension and gross hematuria. He just had a positive history of upper respiratory tract infection 2 weeks ago. His laboratory tests revealed glomerular hematuria, nephrotic range proteinuria, low complement levels (both C3 and C4 levels) and normal renal function. Supportive therapy was started for him but after 4 weeks, clinical symptoms were not resolved and complement levels remained in low levels of normal. Kidney biopsy was performed and findings are compatible with c3 glomerulopathy with membranoproliferative histologic pattern (figure 1). His symptoms were resistant to prednisolone and cyclosporine therapy, and two months later he showed pluresia and non-infected skin lesions in both legs.A 3.5year old boy presented with failure to thrive. He had a history of congenital hypothyroidism that was under therapy with levothyroxine. There was absent metacarpal of left thumb that was reconstructed by Oscuneiform bone graft (Fig.1) A café-au-lait spot was detect on suprapubic region. The initial lab test revealed mild thrombocytopenia. eGFR was 75 ml/min/1.73m2 . Renal ultrasound showed that both kidneys were smaller than normal for age with mild hydronephrosis in left pelvic kidney. Tc 99m -DMSA renal scintigraphy con irmed left ectopic kidney (Fig.2)Introduction: Urinary tract infection (UTI) is a common pediatric problem. It has been estimated that 8% of girls and 2% of boys suffer from UTI during childhood. So, prevention of scar formation in high risk children is very important. This study was performed to evaluate the causes of recurrent urinary tract infection in children on prophylaxis. Materials & Methods: This study was performed on 141 cases in 126 children with recurrent UTI. A questionnaire was prepared and data including sex, age, grade of vesicoureteral reflux, and antibiotic used for prophylaxis were collected. Results: The mean age of the patients was 46.6±41.1 months; 24 % of the participants were male and 76% were female. The most common predisposing factor of recurrent UTI was vesicoureteral reflux. E.coli was the microorganism responsible for most of the cases (85.5%). In 85.5% of the children, Co-trimoxazole was used as prophylaxis. Drug resistance was the most common reason of recurrence. Conclusions: We conclude that girls are at higher risk of recurrent infection and regarding the high prevalence of Co-trimoxazole resistance, administration of this drug should be limited and with caution. Keywords: Urinary tract infections; Vesico-Ureteral Reflux; Drug resistance; ChildStreptococcal pharyngitis is common in the pediatric age group. Although its treatment is simply achieved by administration of a single dose of benzathine penicillin, oral penicillin for 10 days, or azithromycin for 5 days, it has serious complications such as rheumatic fever (RF) and chorea if left untreated. Treatment of pharyngitis does not prevent glomerulonephritis but prevents the spread of streptococci that can cause an epidemic in glomerulonephritis if they are of the nephritogenic strain. Post Streptococcal Glomerulonephritis (PSGN) is common in school age children and usually has a benign course as more than 95 percent of the cases recover the acute phase and less than 5 percent progress in their course to Rapidly Progressive Glomerulonephritis (RPGN) and ultimately about one percent develop End Stage Renal Failure (ESRF). Herein, we present a 12-year-old male with a history of untreated streptococcal pharyngitis who first came to our clinic with a history of arthralgia and arthritis, fatigue, hematuria, petechia, purpura, elevated levels of Blood Urea Nitrogen (BUN) and Creatinine (Cr), and low grade fever. Echocardiography revealed endocarditis which was treated. However, renal failure required renal replacement therapy (RRT), and massive proteinuria needed renal biopsy which revealed membrano proliferative glomerulonephritis (MPGN).

For example, the birth of a sibling, a divorce, or a death in the family may cause a child to act out. Behavior disorders are more serious. They involve a pattern of hostile, aggressive, or disruptive behaviors for more than 6 months. The behavior is also not appropriate for the childs age. Nocturnal enuresis (NE) is one of the most frequent pediatric pathologies. The prevalence of primary nocturnal enuresis (PNE) is around 9% in children aged 5-10 years and about 40% of them have one or more episodes per week. nMaterials and Methods: in this study, we recruited 146 children with MPNE and 146 healthy children without MPNE aged 6-18 years old. The children behavioral checklist for children behavioral assessment was completed by the parents. Data was analyzed using ANOVA and chi- square tests. nResults: Among 292 children in both groups, somatic complaints, thought problems, delinquent problems, social problems, and ADHD were not significantly different between cases and controls while internalization, externalization, anxiety-depression, aggressive behaviors, isolation-depression, and affective-behavioral problems were significantly different. nConclusions: Considering the results of this study, the higher prevalence of behavioral problems in children with MPNE highlights the importance of early intervention for better treatment and prevention of behavioral problem in children. nKeywords: Emotional Disturbances; Nocturnal Enuresis; Child.March 12, 2015 will mark the 10th anniversary of World Kidney Day (WKD), an initiative of the International Society of Nephrology and the International Federation of Kidney Foundations. Since its inception in 2006, WKD has become the most successful effort ever mounted to raise awareness among decision-makers and the general public about the importance of kidney disease. Each year WKD reminds us that kidney disease is common, harmful and treatable. The focus of WKD 2015 is on CKD in Disadvantaged Populations. This article reviews the key links between poverty and CKD and the consequent implications for the prevention of kidney disease and the care of kidney patients in these populations.Introduction: Magnetic Resonance Urography (MRU) is a popular method for identifying uropathies in children. Some children are not cooperative for such examinations and are sedated. We decided to evaluate the effects of midazolam as a sedative drug on ureter visualization in patients undergoing MRU. Materials and Methods : The study was conducted in Paytkaht Medical Imaging Center, Tehran, Iran. Two hundred and three children with urologic diseases were divided into 2 groups. Patients in the non-cooperative group received midazolam prior to MRU. Results: Our findings showed that non-cooperative children had a better ureter visualization on MRU (P<0.01). Conclusions: Midazolam increased ureter visualization possibly by reduction in the ureter peristaltic motility. Therefore, its use could shorten the duration of MRU. It is beneficial to use midazolam in all children who undergo MRU. Keywords :xa0 Diagnostic Imaging , MRI; Urography; Midzolam; Child; Ureter.

The pattern of renal disorders in Calabar was studied 16 years prior to the current study. This review is aimed at revealing any change in the pattern of renal disorders in Calabar 16 years after the first study. Materials and Methods : This study was carried out by analyzing case notes of children admitted to the pediatric medical ward of University of Calabar Teaching Hospital, Calabar, Nigeria between January 2006 and December 2016. Results:xa0 Of 8,711 children admitted during these ten years, 216 (2.5%) had renal disorders. Acute glomerulonephritis (AGN) was the commonest renal disorder observed in 64 (29.6%) cases followed by urinary tract infection (UTI) (n=60, 27.8%) and nephrotic syndrome (NS) (n=49, 22.7%). Other diseases included nephroblastoma, chronic renal failure, acute renal failure, and posterior urethra valves. Similarly, the above findings were seen in our previous study with AGN being the commonest followed by NS and then UTI. Other findings in this study, including polycystic kidney disease, renal calculi, hemolytic uremic syndrome, HIV, and sickle cell nephropathies, were not seen in the previous study. The case fatality rate was 1.9%, which was mainly due to the complications of acute nephritis. Conclusions: AGN still remains the commonest renal disorder in Calabar and UTI is now the second commonest renal disease. The spectrum of renal diseases in Calabar is expanding, including polycystic kidney disease, calculi, hemolytic uremic syndrome, HIV, and sickle cell nephropathies. Keywords : Changing Pattern; Renal disorders; Calabar; Children.. Aphallia (total absence of penis) is an extremely rare abnormality that can be part of the urorectal septum malformation sequence. We are reporting a 40-day-old boy who was referred to our nephrology clinic due to the absence of the penis and urinating through the rectum. He was born to a 17-year-old mother and a 24-year-old father, and was delivered term via normal vaginal delivery. The pregnancy was uncomplicated with no maternal toxin or medication exposure. Both parents were healthy and there was no family history of congenital abnormality. The parents were also unrelated. Physical examination revealed agenesis of the penis, a normal scrotum, and bilateral normally positioned testises. Moreover, the heart, lungs, abdomen, head and neck, and spinal column were all normal on examination. The karyotype was 46XY and the gender was male. Initial ultrasonography one week after birth revealed moderate bilateral hydronephrosis but the last ultrasonography 45 days later revealed only mild fullness of both kidneys. Keywords: Aphallia; Gender; penile agenesis.We report a case with Wilson’s disease who developed nephrotic syndrome one year after starting D-pencillamine. After stopping D-penicillamine, only zinc was given for maintenance. His proteinuria resolved after four weeks of full dose prednisolone administration and three intravenous methylprednosolone injections for nephrotic syndrome. Membranous glomerulopathy is most commonly associated with nephrotic syndrome secondary to D penicillamine but isolated cases of minimal change lesions are also reported like our case. The most likely cause of nephrotic syndrome in this child was the late complications of D-penicillamine. It also reemphasizes the importance of early monitoring for proteinuria and the need to shift to an alternative agent if side effects develop. Keywords: Nephrotic syndrome; D-pencillamine; Wilson’s disease.Ischemia reperfusion damage usually occurs after renal transplantation. These injuries can stimulate the innate immune system, trigger an inflammatory response and ultimately activate the adaptive immune system. These events may result in rejection, graft fibrosis and chronic allograft nephropathy. Different mechanisms contribute to innate immune system activation following ischemia reperfusion injury in renal transplants. Some of these mechanisms are known and described by investigators while the remainin g are still unknown. To clarify the precise mechanisms underlying the innate immune system activation and rejection progression helps us to plan therapeutic protocols to reduce immunologic responses to ischemic events and to improve the graft function andoutcome. In this review, we will discuss how innate and adaptive immune systems are activated during an ischemic insult and thereafter discuss related therapeutic interventions to block the activating pathways.A 3-year old boy with fever (40°), chill, malaise, nausea and vomiting from 5 days ago came to pediatric clinic. He had no positive past medical history. His lab data revealed marked leukocytosis with ESR:115 and CRP:102. His urine analysis was in favor of urinary tract infection and urine culture was positive. Because of sonography report, spiral CT scan with contrast was done. What is your diagnosis?Introduction: Steroid resistant nephrotic syndrome due to idiopathic focal segmental glomerulosclerosis (FSGS) or genetic mutations is one of the most common causes of end-stage renal disease (ESRD) that leads to renal transplantation. The relapse of the disease in the transplanted kidney, despite proper therapeutic management pre and post transplantation, may result in graft loss. Lack of accurate data about the status of transplanted patients due to FSGS encouraged us to obtain data from all pediatric nephrologists in Iran to achieve better pre and post transplantation therapeutic management. Material and Methods: The personal data of the pediatric nephrologist as well as the data of surgical and medical management prior to transplantation, relapse in the allograft kidney, and the therapeutic response rate after relapse were collected via a questionnaire. Results: Of 82 cases of FSGS from 1998 to 2018, 23 had relapse, mostly within 1 year after transplantation. When relapse occurred, nearly all centers used plasmapheresis and rituximab and some used angiotensin converting enzyme inhibitor (ACEI) or angiotensin receptor blocker (ARB) in addition to immunosuppressive medications and methyl prednisolone pulse therapy. Genetic studies were done in only two centers and there was no difference in immunosuppressive medications between these two centers and the idiopathic group. Pre-transplant plasmapheresis and rituximab were administered in four centers, while two centers used IVIG and one center only used plasmapheresis. Delayed graft function (DGF) was negative in 7 and positive in 9 centers. In most centers, immunosuppressive therapy consisted of a corticosteroid, mycophenolate mofetil, and tacrolimus. Relapse and recovery rates varied from less than 10% to more than 50% in all centers. Seven centers had no response to any medication. The lowest relapse rates were seen in two centers that had deceased donors and used rituximab and plasmapheresis prior to transplantation. Conclusion: It can be concluded that with regard to the possibility of relapse after transplantation and variable therapeutic management modalities before and after transplantation, it is reasonable that genetic analysis of mutations, identification of idiopathic and high-risk cases, and use of appropriate therapeutic protocols should be considered to decrease the relapse rate. Keywords: FSGS; Renal transplantation; Nephrotic syndrome; Child.Ureteral ectopia is a common condition presenting as incontinence in females and incidentally detected in males. The diagnosis requires thorough radiological investigations to delineate the anatomy and formulate the treatment. The prognosis is generally excellent. We presented a series of three cases of ureteral ectopia and discussion regarding their management. Keywords: Female; Urinary Incontinence; Ectopic Ureter; Duplex Moiety Kidney.Congenital Nephrotic Syndrome (CNS) is an autosomal recessive (AR) disorder characterized by massive proteinuria, hypoalbuminemia, and severe edema, starting in the first 3 months of life. Intussusception on the other hand is a surgical condition requiring a leading point in most of the cases. The occurrence of intussusception in congenital nephrotic syndrome may be due to bowel edema as the leading point. In this report, we present monozygotic twins with congenital nephrotic syndrome, who experienced the first episode of intussusception at ten months of age and then had repeated episodes until they were 18 months old. In our patients, mesenteric lymphadenopathy was reported by a radiologist that could serve as a leading point. Upon laboratory examinations, we could not find any explanation for this report. Intussusception must be one of the differential diagnoses of abdominal pain in nephrotic syndrome patients since prompt diagnosis and appropriate treatment can prevent further complications.

The epidemiology of AKI has been changing over years. The aim of this study was to evaluate the epidemiology of AKI in hospitalized children in Iran. A literature search from March 2000 to March 2014 was conducted through MEDLINE, EMBASE, Scholar.google, IranMedex, MagIran, SID, and manual reference search of identified articles. Retrospective and prospective cross-sectional studies with a clear definition of acute kidney injury or failure were included. Seven out of twenty three articles which were found met the criteria. The incidence of AKI declined from 36% (2006-2008) to 15.4% (2010-2011) in the PICU setting of three referral teaching hospitals in Tehran. According to the classification, 10% had pre-renal failure, 86% had intrinsic renal failure, and 4% had post-obstructive uropathy. Follow-up was limited to the days of hospitalization. The overall reported mortality rate was 18% in pediatric departments. Acute glomerulonephritis including hemolytic uremic syndrome was the most common underlying disease (46.5%). Acute tubular necrosis was reported in 33% of the cases. One third of the cases of acute renal failure occurred in children less than two years. The real incidence of acute kidney injury might be higher considering a unified standard definition. Acute glomerulonephritis and acute tubular necrosis comprised the majority of the etiologies.

She was treated with plasma infusion followed by plasmapheresis and peritoneal dialysis. After two months, she was discharged in remission undergoing periodic plasmapheresis. Four months later, she was visited for fatigue, tachypnea, and palpitation. Cardiac evaluation revealed dilated cardiomyopathy with an ejection fraction of 15-20%.xa0 She was hospitalized and treated with inotropes and diuretics; one week later, she was discharged in a favorable condition. After six months follow-up, she showed an acceptable renal and cardiac state. It seems that cardiomyopathy can occur as a late and rare complication of HUS. We recommend cardiac evaluation for all patients with HUS at its presentation and in later follow-ups.xa0xa0 Keywords: Cardiomyopathy; Hemolytic Uremic Syndrome; Child.A 4-year-old male was transferred to pediatric emergency room because of acute abdominal pain. He was healthy before and had a history of felling down 2 weeks ago. Physical examination revealed an anxious and ill child with temperature of 37.5°C, pulse of 102/min, respiratory rate of 28/min and blood pressure of 100/70 mmHg. In abdominal exam the patient showed signs of acute abdomen. He was transferred to operating room and the first surgical diagnosis was kidney hematoma. Post operation kidney ultrasound reported large unilateral kidney hematoma. Post operation abdominal CT scan was shown in (Fig.1) (a,b).Introduction: Chronic kidney diseases are associated with a poor quality of life in patients and their families. Previous studies have shown a three-fold higher rate of exhaustion in peritoneal dialysis compared to hemodialysis patients and their families. Here we studied the quality of life and caregiver’s burden of children receiving chronic ambulatory peritoneal dialysis (CAPD) in comparison with other chronic diseases among pediatric patients. Materials and Methods : This prospective case-control survey was conducted between 2013 and 2014 in Ali- Asghar Children’s Hospital. The inclusion criteria were age below 18 years and having a chronic disease diagnosed at least six months earlier. The parents of 13 children on peritoneal dialysis (cases) and 160 children with other chronic diseases(controls) were requested to complete the Pediatric Quality of Life Inventory (PedsQL™ 4.0™) appropriate to the patient’s age and the Caregiver Burden Scale (CBS).xa0 Independent t-test was applied to compare the variables between the two groups. P-values < 0.05 were considered significant. Results: Overall, 353 questionnaires were completed. The CAPD group had a higher mean (SD) score of quality of life in all domains, including somatic symptoms [67 (25.6) vs. 18.5(15.6)], emotional symptoms [71(17) vs. 20.5(15.1)], and social functioning [58(32) vs. 21.3(20)] (p-value<0.001). In addition, the case group had a lower mean (SD) score of caregiver’s burden [50(16.7) vs. 80 (13.5)] compared to the control group (P value<0.001). Conclusions: CAPD children and their parents had better a PedsQL™ 4.0™ score and a lower CBS compared to children with other chronic diseases. The most affected area of the quality of life was school functioning in the CAPD group and somatic symptoms in the control group. Keywords : Quality of life; Renal Dialysis; Adaptation; Psychological; Chronic Disease; Child.A 3-year-old girl was admitted with typical hemolytic uremic syndrome (HUS) and conservative treatments were initiated. During hospitalization, she had seizures, right hemiparesis, and loss of consciousness. Initial MR of the brain showed changes of acute disseminated encephalomyelitis (ADEM). She was treated with intravenous methylprednisolone and immunoglobulin. Upon improvement of her clinical condition, she was discharged with oral prednisolone which was tapered after two months. After one year fallow-up, the child now has a normal renal function and normal neurodevelopment.We report a six-year-old female child whoxa0 presented with continued incontinence and a normal physical examination. Urodynamic study was normal and uroflowmetry showed a prolonged low peak flow rate (PFR) in voiding. VCUG revealed left grade ш VUR. Her symptom continued in spite of medical treatment. Finally, MRU showed a single system ectopic ureter with a dysplastic kidney on the right side and a refluxing duplex kidney on the contralateral side. She underwent surgical correction and recovered.

Bladder Volume Wall Index in Children with Urinary Tract Infections. J Ped. Nephrology 2013 July;1(1):18-22. Introduction : Few studies have focused on the correlation between bladder ultrasound and urinary tract infection. The aim of this study was to evaluate the bladder volume wall index in children with single or recurrent urinary tract infection. Materials & Methods : This case-control study was conducted between March 2008 and December 2009. The study was performed on one hundred children (8 boys, 92 girls) aged 4-15 years with a history of urinary tract infection and thirty-nine (20 males, 19 females) age- matched healthy children who had negative urine culture one month before investigation. The kidneys, ureters, and bladder sonography were performed in all children. Bladder volume wall index was calculated for each child and the result of 70-130 was presumed normal. Student T-test, chi-square, likelihood ratio, and risk ratio were used. P-value 130) in 38 children (28 cases, 10 controls) (P>0.05). The median residual volume was not different between the two groups. The abnormal BVWI in children with vesicoureteral (VU) reflux was 75% as compared to 51% in those without VU reflux (P>0.05). There was no correlation between BVWI and age, gender, groups, vesicoureteral reflux status, or residual volume (P>0.05). Conclusions : According to our findings, the bladder volume wall index is not sensitive enough to discriminate children who are prone to urinary tract infection. Keywords : Urography; Urinary Tract Infections; Ultrasonography; Urinary BladderAllergic diseases have increased in prevalence during recent years. Although they impose numerous health and financial burden on patients and their family and also the society, they are to some extent preventable and manageable. While reviewing the literature to find any relationship between allergic disease as the familiar and preventable conditions and the two unfamiliar entities, named Eosinophilic Cystitis (EC) and Interstitial cystitis(IC); a significant number of reports were found about the etiological roll of atopy and allergy in the development of these conditions.xa0 Nevertheless this relationship is stronger concerning IC than EC. Referring to allergy as a contributing factor makes it more understandable and controllable. Although in order to reach a proper conclusion more thorough studies are required.

Sodium is unique among electrolytes because water balance, not sodium balance, usually determines its concentration. Although water balance is usually regulated by osmolality, volume depletion stimulates thirst, renal protection of water and ADH secretion. Volume reduction has priority over osmolality; volume depletion stimulates ADH secretion, even if a patient has hyponatremia. The aim of this study was to consider scar nephropathy in children with UTI and hyponatremia and compare it with children without hyponatremia. nMaterial and Methods: 200 children with pyelonephritis were included in this case–control study as case and control groups, respectively. Subjects were selected from children referred to the pediatric clinic of our hospital in Arak, Iran. Case group included children with hyponatremia and UTI (with VUR) and control group included children with UTI (With VUR) and normal serum sodium. Data was analyzed using SPSS ver.18 nResults: Among 200 (100%) children in both groups, 5 children (5%) had normal sodium and reflux nephropathy and 23 children had hyponatremia and reflux nephropathy. nConclusions: Hyponatremia in children with reflux nephropathy was significantly more common than children without reflux nephropathy. The observed correlation between reflux-related injury and hyponatremia necessitates evaluation of electrolytes in children with pyelonephritis. nKeywords: Pyelonephritis; Child; Hyponatremia; Vesico-Ureteral Reflux.Despite being one of the major health problem globally, tuberculosis still remains an important, but under diagnosed and ignored cause of kidney damage especially in resource poor settings. Timely diagnoses and treatment can cure this otherwise devastating resource draining ailment. We report a 10-year-old girl who had persistent pyuria and dysuria despite receiving multiple drugs empirically before antitubercular therapy was initiated.xa0 Keywords : Child; Renal Tuberculosis; Urinary Tract infections.Introduction: Urinary Tract Infection (UTI) is one of the most common pediatric infections. UTI may create cystitis or pyelonephritis by involving bladder or renal parenchyma, respectively. Pyelonephritis, especially in pediatric patients, can lead to scar formation in kidneys and consequent complications such as hypertension, proteinuria, dysfunction and chronic renal insufficiency. The current study aimed to determine risk factors of acute rental cortical lesions in renal scintigraphy in children with UTI. Materials and Methods : Fifty-three patients with significant renal cortical lesions and 53 cases without significant renal cortical lesions were compared based on the intensity of findings of DMSA scintigraphy within the first two weeks of diagnosis. Patients were divided into three groups of 1 month to 2 years, 2 to 4 years and 4 to 10 years. Results: Of 106 patients, 11 males (20.8%) and 42 females (79.2%) had significant acute renal cortical lesions, whereas 15.1% of males and 84.9% of females had no significant acute renal cortical lesions. There was a significant difference in the degree of fever, the average interval between the onset of fever and treatment, mean level of CRP, leukocytosis and ESR in the two studied groups. The presence of Vesicoureteral Reflux (VUR), low initial hemoglobin and low initial BMI as random findings were associated with significant renal cortical lesions. Gender, age, grade of VUR and type of organism in urine culture had no significant association with significant renal cortical lesions. Conclusions: In this study, delaying in treatment, high degree fever, leukocytosis, high initial ESR and CRP, existence of VUR and low initial BMI and hemoglobin levels were associated with an increase in the value of acute renal cortical lesions, so in these cases, DMSA scan is suggested.

It is characterized by deficient renal reabsorption of sodium and chloride, which results in a group of certain symptoms. Different types of BS can be distinguished from different clinical manifestations, and most importantly, via analyzing possible affected gene(s) for its confirmation. A close associated syndrome which was primarily considered as a mild variant of BS, Gitelman syndrome (GS), is characterized by hypokalemicxa0 metabolic alkalosis xa0with hypocalciuria, and hypomagnesemia. In this review, we discuss different features of BS and also GS, including clinical and genetic alterations which correspond to each type. Keywords: Bartter Syndrome; Molecular Genetics; Child.

Neurologic examinations, lumbar puncture analysis, and electroencephalogram were normal but magnetic resonance imaging of the brain showed dilated ventricles and sulci. Despite standard induction therapy, the patient gradually entered a confusional state, disorientation that changed to abnormalities in verbal and working memory, and finally no verbal communication for several days and avoided eating food and taking oral drugs. The patient achieved partial remission of the disease (improved symptoms of psychosis and renal function despite a high titter of anti-double strand DNA and positive anti-nuclear antibodies) with plasmapheresis, intravenous immunoglobulin, and anti-psychotic medication. Our case is interesting because he was refractory not only to standard treatments, but also he did not respond to therapeutic options that are used in refractory systemic lupus erythematosus and presented with psychosis that is an unusual clinical presentation in SLE .

The purpose of this study was to investigate the frequency, cause, and outcome of hAKI in critically ill children in a tertiary level hospital. Materials and Methods : In this prospective cross-sectional study, a total 36 critically ill patients with hAKI were analyzed. hAKI was diagnosed according to the AKIN criteria. The clinical data of the patients admitted to the Pediatrics and Allied Departments in this hospital from November 2014 to October 2015 were collected. Results: A total of 3950 patients were admitted during the study period and 1103 (27.9%) were critically ill patients. Among the critically ill children, 36 (3.3%) were diagnosed with hAKI. Among different age groups, the highest incidence (5.05%) of hAKI was seen in children aged above 10 years. Sepsis was the major cause of hAKI accounting for 44.1% followed by antibiotics (27.1%), hypovolemia (13.6%), nephrotoxic agents (10.2%), and contrast agents (5.0%). Renal replacement therapy was required only in 8.3% of the cases. Conclusions: In comparison to other studies, this study showed a low incidence of hAKI where ICU facilities are limited. Among the hospital admitted critically ill patients, a significant number of patients may develop AKI mostly due to sepsis and use of antibiotics. Keywords : Hospital acquired AKI; Sepsis; Critically ill children; IncidenceIntroduction: Urinary Tract Infections (UTIs) are common in childhood and are frequently associated with abnormalities of the urinary tract. UTIs are the leading cause of morbidity in patients with neurologic bladder; this causes recurrent UTIs and Chronic Kidney Injury& Disease (CKD) that affects their quality of life. Children with UTIs are mostly neurologically intact, but may have infections as a result of a voiding dysfunction. The present study aimed to examine the relationship between occult bladder dysfunction and recurrent UTIs in our patients. Material and Methods : A cross-sectional study was done on 210 children aged 10 months to 15 years presenting with UTI with/without reflux who were admitted to the Nephrology Ward of Mofid Children’s Hospital between April 2011 and September 2013 using convenient sampling. Statistic analyses were conducted using descriptive statistics, Kolmogorov-Smirnov test, Mann Whitney test, Fisher’s Exact test, and odds ratio, and p values <0.05 were considered significant. Results: Of 210 Children 74% were female and 26% were male. 25% had one, 25% had two, 31% had 3, and 19% had more than 3 episodes of UTI. Eighty percent of the female and 56% of the male children had recurrent UTI (P: 0.004, odds ratio: 0.361). Fifty eight percent of the patients had Vesicoureteral Reflux which was bilateral in 34% of them. There was no correlation between UTI and Urinary Reflux (P=0.152, odds ratio=1.591) and also no correlation was detected between urodynamic findings and urinary reflux(P=0.243, odds ratio=1.485). Seventy six percent of the children with recurrent UTI had abnormal urodynamic results. Conclusions: Since many children with recurrent UTI and multiple renal scars have bladder dysfunction, it is recommended that urodynamic studies should be included in the evaluation of every child with recurrent UTI and renal scar. Keywords : Urinary Tract Infections; urodynamics; Vesico-Ureteral Reflux; ChildIntroduction: The opioid overdose epidemic is a worrying and considerable public health problem in many countries. A few studies have been done in children about opioid poisoning. The aim of this study was to explain the clinical symptoms and laboratory findings of opioid poisoning and the associated complications among children. Material and Methods : This prospective cross-sectional study was conducted on 100 children under 14 years of age who were poisoned with opium, tramadol, buprenorphine, methadone, and diphenoxylate and admitted to Loghman-Hakim Hospital, a major center for poisoning treatment in Tehran, Iran, from April 2011 to April 2012. The exclusion criteria were a history of musculoskeletal diseases, concurrent ingestion of other drugs, intramuscular injection, and a history of trauma. The clinical presentation and renal and electrolytes complications were recorded. Results: Finally, 90 out of 100 admitted children were eligible to be included in the study, 64 boys and 26 girls (median age: 40.3 ± 32 months, range: 1 month to 11 years old). The minimum duration of admission was 1 day and the maximum was 29 days with a mean of 2 days. The major opioid substance was methadone. The most common symptom was decreased consciousness followed by bradypnea. The incidence of opioid- induced rhabdomyolysis was 2.2% but none of the them were complicated with acute renal failure or electrolyte disturbance. Conclusions: Concerning this study, we recommend attention to muscle enzymes elevation and preventive spadework for its complications in children poisoned with opoiods.

In children with a febrile urinary tract infection (UTI), those with re_lux are 3 times more likely to develop renal injury compared to those without reflux. Reflux nephropathy was once accounted for as much as 15-20% of end-stage renal disease in children and young adults. With greater attention to the management of UTIs and a better understanding of reflux, end-stage renal disease secondary to reflux nephropathy is uncommon. Reflux nephropathy remains one of the most common causes of hypertension in children. Reflux in the absence of infection or elevated bladder pressure does not cause renal injury. We sought to determine the association of infantile reflux nephropathy (IRN) with prenatal risk factors. nMaterials and Methods: In this study, 96 infants with re_luxrelated renal injury and 96 infants with VUR without re_lux nephropathy were evaluated. Maternal information was assessed. Data was analyzed using SPSS version 18. nResults: The results of this study showed that age more than 35 years, pre-gestational hypertension, preeclampsia and eclampsia, preterm delivery, very low birth weight (VLBW), pre gestational diabetes mellitus, and maternal BMI<18.5kg/m2 (underweight) were prenatal risk factors for infantile reflux nephropathy. nConclusions: The data suggests that prenatal factors may affect the risk of IRN. Adequate prenatal care and good maternal support can be effective in the prevention of reflux-related renal injury. nKeywords: Vesico-Ureteral Reflux; Risk Factors; Prenatal; Infant.Introduction: Pediatric urolithiasis is an uncommon disease with incidence varying widely throughout the world. We present our experience in pediatric PCNL in 20 pediatric patients with urolithiasis. Materials and Methods : Case records of all patients under 14 years of age who presented with urolithiasis from 2016 March to February 2017 were retrospectively reviewed and analyzed with respect to demographic details, clinical presentation, stone characteristics, PCNL puncture site, number, stone clearance, ancillary procedures used, complications, and follow-up status of the children. Associated biochemical abnormalities were also reviewed. Results: There were 25 renal units in 20 patients (5 had bilateral stones). The mean age at presentation was 8.4 years. There were 15 males and 5 females. The most common presenting symptom was flank pain (n=19/20). There were solitary stones in 17 renal units: 2 stones in 6 renal units and multiple stones in 2 renal units. The average stone size was 1.5cm. Four patients had staghorn calculi. Five patients required two punctures of whom 3 had bilateral disease and 2 had staghorn calculi. The sheath used ranged from 18 Fr to 22 Fr. The nephrostomy tube and DJ stent were kept in all patients. The duration of the procedure at a single site ranged from 45 minutes to 75 minutes. Complete clearance was achieved in 19 patients while one patient required bilateral URS. Three patients had mild fever post-operatively. None of the patients required blood transfusion. Hypocalcaemia was detected in 7 patients. Conclusions: PCNL is safe and effective for treating urolithiasis in children. Keywords : PCNL; Urolithiasis; Pediatric.

A rare presentation of cystic nephroma in a young adult

Cystic nephroma is a rare benign renal lesion with non-specific presenting symptoms. This tumour has a bimodal age distribution presenting in children between 3 months and 2 years and in adults over 30 years of age. There is male preponderance with a 2:1 male to female ratio in the childhood whereas it is commoner in females in adults. It is uncommon in the age-group of 5 years–30 years. We describe a case of cystic nephroma in a 25-year-old female which was managed by partial nephrectomy.

A case of cystitis cystica presenting as a bladder mass in a boy

Cystitis cystica is a rare proliferative lesion of the bladder, usually caused by chronic irritation and inflammation. It is caused by the hyperplasia of the submucosa and proliferation of von brunn nests of the bladder. Though usually benign, it is considered to have some malignant potential. This condition has been reported in adults, but is rarer in pediatric age group. We describe the case of cystitis cystica in a 13 year-old boy who presented with painless hematuria and was suspected to be bladder neoplasm on imaging.

Anterior urethral valve, a rare cause of bilateral vesicoureteral reflux in a two year old boy: A case report and a review of the literature

Anterior urethral valve (AUV) is a rare cause of obstructive uropathy in children. These are much rarer than posterior urethral valves. We report a case of a child with AUV and high grade bilateral vesicoureteric reflux. He was managed by transurethral laser ablation. The left sided reflux resolved after ablation. The right sided reflux persisted. The child is awaiting ureteric reimplantation.
